the structures that, with the conjunctival sac, produce and provide drainage for lacrimal fluid (tears), consisting of the lacrimal gland, the lacrimal lake, the lacrimal canaliculi, the lacrimal sac, and the nasolacrimal duct.
A diffuser airflow rate is 50 cfm per linear foot (77.4 L/s per linear meter) of diffuser. Therefore, the recommended flow to use when designing is 50 cfm/ linear ft x 0.8 = 40 cfm/linear ft (77.4 L/s/ linear m x 0.8 = 61.9 L/s/linear m). The nominal airflow of a diffuser is determined by multiplying the diffuser length, the number of slots, and the airflow per linear foot. Using the airflow per linear foot calculated above, a 4 foot, 2-slot, 2-way diffuser should be designed to handle 4 linear ft x 2 slots x 40 cfm/linear ft = 320 cfm (1.219 m x 2 slots x 61.9 L/s/linear m = 150.9 L/s). To maximize the effectiveness of ventilation with ceiling diffusers, throws should be kept as long as possible.
The annuallighting cost for that facility was over $8,200.On a watt per square foot basis, the restaurants averaged1.55 watts per square foot. The range was from .44 wattsper square foot to 4.40 watts per square foot.One facilityused compact fluorescent bulbs in the dining area.In Florida restaurants, the availability of air-conditioningis highly essential to business. Lost efficiency in air-conditioning was examined.989,reported the annual Btu per square foot nationwide is590,000 Btu. The 46 restaurants in this study averaged512,568 Btu per square foot.Claar et al. 1985, made a series of general observations inrespect to energy conservation opportunities in their exten-sive end-use monitoring project of restaurants.
